UNITE TATES EDWARD D. MEIER, OF ST. LOUIS, MISSOURI.

STEAM-GENERATOR AND HOT-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 595,641, dated December 14, 1897.

Application filed July 15, 1896. Serial No. 599,209. (No model.)

1'0 all whom it may concern.-

Be it known that I, EDWARD D. MEIER, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Steam-Generators and Tater-Heaters, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part of this specification, in which Figure 1 is a longitudinal sectional view through a steam-generator and water-heater embodying my invention. Fig. 2 is a front elevational view, with the front plate of the water-leg removed, showing a slightly different form. Fig. 3 is a longitudinal sectional View on the line 3 3, Fig. 2. Fig. 4 is a front elevational View, the front plate of the wa terleg being removed, showing a slightly different form; and Fig. 5 is a sectional view on line 5 5, Fig. 4. r

This invention relates to a new and useful improvement in steam-generators and waterheaters of that class known as the Heine type, such as illustrated in United States Letters Patent No. 304,195, granted to Hermann Heine August 26, 1884s.

The object of my present invention is to so construct the front and rear water-legs that the circulating water therebetween and the drum will be unobstructed-that is, the throat area of the water-legs where they connect to the drum will be substantially the same, more or less, as the end area of the drum.

With. this object in view the invention consists in so constructing the front and rear Water-legs that the drum will open thereinto with its full end area. Incidental to this the outer plates of these water-legs are so constructed as to resist thepressure due to this end area. Another feature of the invention resides in arranging strengthening rings around these water-legs, as will hereinafter appear.

Other features of the invention reside in the construction, arrangement, and combination of the several parts, all as will hereinafter be more fully described, and afterward pointed out in the claims.

In the drawings, A indicates the drum, B

the mud-drum, O the steam-dome, and D the water-tubes, all such parts being of wellknown construction.

.The front and rear water-legs being substantially the same I will describe but one of themthe front. 7

E indicates the back or inner plate of the water-leg, which is flanged forwardly at its side edges to meet the front plate, thus formin g a water-space between them. The upper part of this back plate is formed with an opening and flanged, as at F, to which flange is secured the front end of drum A. Gindicates the front plate of the front Water-leg, whose outer or side edges are flanged rearwardly, said flanges meeting the corresponding flanges of said plate E to form the waterspace between them. These flanges are secured together by a strap H.

I indicates suitable stay-bolts, which are arranged between the plates E and G and whose purposes and location are well understood. These stay-bolts extend practically over the entire area of the front and back plates to brace them at all points.

As shown in Figs. 1 and 5, the front plates are bulged outwardly, as at J, in line with the drum in order that the plate may be strengthened at this point, because it is impossible to attach stay-bolts to the inner plates E. In Fig. 3 this front plate is shown flatthat is, the bulge J referred to is not present. In order to further strengthen these plates around the tubes D and hand-holes, I prefer to flange the front and back plates to the rear, as shown in Fig. 3. In some instances it may be desirable to strengthen these plates around the drum A and bulge J, and in order to do this I arrange thereon rings K, through which the circular series of stay-bolts around said parts pass.

Having ,thus described my invention, what I claim, and desire to secure by Letters Patside, said opening having a flanged edge, of a drum whose end fits in said opening and is secured to said flanged edge, and a bulge in the other side or wall of the water-leg, said bulge being in line with the drum; substantially as described.

3. The combination with the iron t and back water-legs which are connected at their lower ends by water-tubes, and a drum connecting the upper ends of the water-legs and opening thereinto with its full end area, said legs being bulged in line with the drum to strengthen the water-legs; substantially as described.

4. The combination with the water-legs, of water-tubes connecting the lower ends of the same, a drum connecting the upper ends of the same, said water-legs being bulged in line with the drum to give them strength, rings around said bulged portion and drum-flange, and stay-bolts; substantially as described.

5. The combination with front and back water-legs, the upper ends of whose inner plates are formed with openings having flanged edges, of a drum fitting in said openin gs and secured to the flanged edges thereof, the lower ends of said inner plates being formed with tube-openings having flanged ed ges,and water-tubes secured in said flanged tube-openings, substantially as described.

6. The combination with the outer plate of a water-leg which is formed with series of inwardly-flangcd hand-holes, the flanges of which afford raised seats for the hand-hole plates, of an inner plate formed with outwardly-flanged holes to afford extended bearings for the water-tubes, Water-tubes in the outwardly-flanged openings of the inner plate, and stay-bolts connecting said outer and inner waterleg plates; substantially as described.

In testimony whereof I hereunto aflix my signature, in presence of two Witnesses, this 27th day of June, 1896.

EDVARD D. MEIER.
